Filter by:People sometimes report that their relatives who have been diagnosed with Parkinson's disease (PD) have a unique smell. A previous study has demonstrated that PD patients do have smell that is different from that of healthy people. Sniffer dogs have long been used to identify criminals, and recently been used to identify subject with cancer. The investigators hypothesized that sniffer dogs may be able to identify PD patients.
The purpose of this study is to determine and compare the effectiveness of WalkingTall-PD (the new intervention) against Mobility-plus (a PD appropriate exercise program) with respect to stabilizing gait, reducing step-time variability, preventing falls and enhancing independence in people with Parkinson's disease. WalkingTall-PD is a novel neuro-rehabilitation program delivered through a tablet/smart phone and smart socks for people with Parkinson's disease that aims to improve mobility and reduce falls. WalkingTall-PD combines a variety of PD-specific rhythmic stimuli (auditory, visual and haptic cues) which are synchronised with high intensity stepping, walking and balance training. Mobility-plus is a "pseudo placebo" comparator program using non-slip socks, a low intensity paper-based exercise program and health information specific to Parkinson's Disease.
The aim of this project is to measure behavioural disorders in Parkinson's disease (PD) patients in a more objective way, in order to facilitate the detection of those symptoms and improve the treatment of non-motor symptoms in Parkinson's disease.
Patients with atypical parkinsonism often show gait and mobility impairment manifesting in early disease stages. In order to maintain mobility and physical autonomy as long as possible for these patients, we will examine the effect of two types of physiotherapy in patients with multiple system atrophy (MSA), progressive supranuclear gaze palsy (PSP) and idiopathic Parkinson's disease (IPD). The study is divided into an ambulant daily in-patient physiotherapy phase, followed by a home-based training phase. At the beginning and the end of the study, the patients daily activity will be recorded for one week using Physical Activity Monitoring (PAM) sensors. The aim of this double-blind, randomized-controlled study is to determine effective physiotherapy in patients with atypical parkinsonian syndromes in order to maintain mobility for as long as possible.
Retrospective, monocentric, observational study designed to evaluate the effects of Bilateral Subthalamic Nucleus Deep Brain Stimulation (DBS STN) on Neuropsychiatric fluctuations in Patients with Parkinson's Disease (PD)
Activation is the amount of voluntary recruitment of a muscle during voluntary contraction. Full activation implies the recruitment of all muscle fibres at their tetanic frequency. In healthy subjects, and even in sports performances, full activation may be rarely achieved despite a subjectively maximal effort. Highly decreased activation has been observed in patients affected by various orthopaedic and neurological disorders. In these subjects, paresis may be caused or aggravated by primitive impairments of the central nervous system and/or, by stimuli arising from peripheral damaged tissues that inhibit the corticospinal or the intraspinal recruitment of motoneurones ("arthrogenous muscle weakness"). There are numerous investigations in the literature on activation measured during isometric contractions, while they are substantially missing as far as isokinetic concentric contractions are concerned. There are reasons to suppose that, contrary to what has been demonstrated for healthy subjects, in patients with various motor impairments the activation is diminished the more, the higher is the joint rotation speed. The present study aims to investigate the amount of activation of the quadriceps femoris during subjectively maximal isometric contractions at 40° knee flexion (0°=complete extension) and isokinetic concentric contractions at an angular velocity of 100°/s in patients with various orthopaedic and neurologic conditions. Activation will be measured on an isokinetic dynamometer, through the "interpolated twitch technique". This consists of stimulating a representative sample of the muscle belly through an electric shock. If the shock does not generate an extra force during contraction, all muscle fibres belonging to the sample reached by the electric shock can be claimed to be recruited at their tetanic frequency. Otherwise, following the stimulus, a twitch can be observed revealing submaximal voluntary recruitment of the muscle.
Implicit motor sequence learning (IMSL) is a form of cognitive function that is known to be directly associated with impaired motor function in Parkinson's disease (PD). Research in healthy young participants shows the potential for transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique, over the primary motor cortex (M1) to enhance IMSL. tDCS has direct effects on the underlying cortex, but also induces distant (basal ganglia) network effects - hence its potential value in PD, a prime model of basal ganglia dysfunction. To date, however, only null-effects have been reported in persons with PD. In the present study, the investigators will investigate the potential of tDCS delivered over M1 to enhance IMSL, as measured by the Serial Reaction Time task, in persons with PD. The investigators will determine immediate effects that may occur concurrently with the application of tDCS but also short-term (five minutes post-tDCS) and long-term (one week post-tDCS) consolidation effects, as previous studies suggest that tDCS exerts its beneficial effects on IMSL in a consolidation phase rather than in an acquisition phase. Establishing possible consolidation effects is of a particular interest, as long-term effects are vital for the successful functional rehabilitation of persons with PD.
This is a mechanistic study to determine the differential effects of the dopaminergic and cholinergic systems on attention, gait, and balance. The primary goal of the study is to evaluate the relative effects of pedunculopontine nucleus (PPN) and subthalamic nucleus (STN) Deep Brain Stimulation (DBS) on these features in persons with Parkinson's Disease (PD) who are eligible for DBS for improvement of their motor symptoms and exhibit gait instability with falls. Patients will be enrolled and implanted with bilateral electrodes in one of the approved DBS locations (subthalamic nucleus: STN), but additionally electrodes will be inserted into the experimental target, namely the PPN bilaterally.
The goal of this study is to identify reliable markers of LRRK2 activity in human CSF.
Our primary objective in this 10-week pilot study is to demonstrate the feasibility of using videoconferencing technology to provide Parkinson's Disease (PD) patients, alongside their supervising care partners, specialized physical and occupational therapy (PT/OT) focused on neurorehabilitation that ultimately aims to reduce fall risk. This therapy is similar to what a PD patient could receive in-person with neurologic-certified physical therapists and occupational therapists with significant experience working with PD patients and addressing their needs, but it is delivered through a virtual platform. Feasibility is defined by measures of adherence, retention, and safety. The specialized PT and OT measurement tools and strategies used in this study are in-line with the most current formal evidence-based guidelines/recommendations available for therapy in PD: European Physiotherapy Guideline for Parkinson's Disease, Parkinson Evidence Database to Guide Effectiveness (PD-EDGE) Task Force and Guidelines for Occupational Therapy in Parkinson's Disease Rehabilitation. The study duration is approximately 10 weeks of the primary telerehabilitation intervention and a 2 follow-up phone calls at the 3- and 6-month timepoints. There will be one baseline in-person evaluation and one final in-person evaluation following the completion of all televisits. The enrollment target is up to 15-20 patient and care partner (P+CP) pairs, meaning 30-40 subjects total. There are no controls for this study.
